Title
(EN) COMPACT REPRODUCTION OF COMPONENTS
(FR) REPRODUCTION COMPACTE DE COMPOSANTS
Abstract
(EN)
A pickup head (2) for an automatic component assembly machine comprises several pipettes (1) placed next to each other for retaining components (3) at the sucking nozzles of the pipettes. An image of the component is captured by means of a video camera (7) and a lens system (5) to be used in an automatic evaluation (7') of the positions of the components on the pipettes (1). This image is composed by superposing successive images, which are captured of only one component (3) at a time. With a suitable movement of the pickup head (2) between the capturing of the successive images the reproductions of the individual components can be packed closely in the composed image. This results in that the lens system (5) can be adjusted for a larger magnification than if only one image had been captured of all the components (3) at the same time. Thereby a more accurate determination of the positions of the components can be achieved in the evaluation.
(FR)
Tête (2) de prélèvement pour une machine automatique d'assemblage de composants qui comprend plusieurs pipettes (1) placées les unes à côté des autres pour retenir des composants (3) au niveau de la buse d'aspiration des pipettes. Une image du composant est prise à l'aide d'une caméra vidéo (7) et d'un système de lentille (5) destiné à être utilisé dans une évaluation automatique (7') des positions des composants situés sur les pipettes. Cette image est composée par superposition d'images successives d'un seul composant (3) à la fois. Grâce à un mouvement approprié de la tête de prélèvement (2) entre la prise des images successives, les reproductions des composants individuels peuvent être placées de manière serrée sur l'image composée. Il en résulte que le système de lentille (5) peut être réglé en vue d'un agrandissement plus important que si une seule image de tous les composants (3) en même temps avait été prise. Il est donc possible de déterminer avec plus de précision les positions des composants lors de l'évaluation.
